Rubidium Titanyle Phosphate RTP is an isomorph of KTP crystal. RTP is used in various nonlinear and electro optical applications because of its‘ good physical properties in range of 350nm to 4500nm. Compared with KTP, RTP has 1.8 times higher damage threshold. Laser systems with RTP crystals are very reliable because of it high resistivity no induced piezo-electric effect with electrical signals up to 60 kHz.
